Hydraulic Calibration of Pipe Network Model Using An Improved Genetic Technique (Dept.C)

Abstract

This research paper exhibits the development and calibration capability of a computer optimization code, called SO-OPTIM. This code copes with several problems concerning water distribution networks which include: new design, rehabilitation, calibration; optimal scheduling of pumps, optimal operation of pump stations in the presence of water elevated tanks, and optimal pressure regulation. These problems are treated using a powerful genetic algorithm optimization technique which consists of a nonlinear objective functions subjected to both linear and non linear constraints. Different modifications were carried out in the simple genetic algorithm. The mentioned code links the optimization model and a hydraulic solver which applies the principles of a new technique used for pipe network analysis in steady state conditions. The proposed code is applied in two different water distribution networks. The first one is a hypothetical network with synthetic calibration data and the SO OPTIM code is applied to perform extended period calibration. The second network is a real water distribution system of Damnhour city, Egypt, with actual data and field measurements and in this case the code performs steady state calibration.
